+Display Weather Forecast In Your Terminal With Wttr.in
+======
+**[wttr.in][1] is a feature-packed weather forecast service that supports displaying the weather from the command line**. It can automatically detect your location (based on your IP address), supports specifying the location or searching for a geographical location (like a site in a city, a mountain and so on), and much more. Oh, and **you don't have to install it - all you need to use it is cURL or Wget** (see below).
+
+wttr.in features include:
+
+  * **displays the current weather as well as a 3-day weather forecast, split into morning, noon, evening and night** (includes temperature range, wind speed and direction, viewing distance, precipitation amount and probability)
+
+  * **can display Moon phases**
+
+  * **automatic location detection based on your IP address**
+
+  * **allows specifying a location using the city name, 3-letter airport code, area code, GPS coordinates, IP address, or domain name**. You can also specify a geographical location like a lake, mountain, landmark, and so on)
+
+  * **supports multilingual location names** (the query string must be specified in Unicode)
+
+  * **supports specifying the language** in which the weather forecast should be displayed in (it supports more than 50 languages)
+
+  * **it uses USCS units for queries from the USA and the metric system for the rest of the world** , but you can change this by appending `?u` for USCS, and `?m` for the metric system (SI)
+
+  * **3 output formats: ANSI for the terminal, HTML for the browser, and PNG**.
+
+
+
+
+Like I mentioned in the beginning of the article, to use wttr.in, all you need is cURL or Wget, but you can also
+
+**Before using wttr.in, make sure cURL is installed.** In Debian, Ubuntu or Linux Mint (and other Debian or Ubuntu-based Linux distributions), install cURL using this command:
+```
+sudo apt install curl
+
+```
+
+### wttr.in command line examples
+
+Get the weather for your location (wttr.in tries to guess your location based on your IP address):
+```
+curl wttr.in
+
+```
+
+Force cURL to resolve names to IPv4 addresses (in case you're having issues with IPv6 and wttr.in) by adding `-4` after `curl` :
+```
+curl -4 wttr.in
+
+```
+
+**Wget also works** (instead of cURL) if you want to retrieve the current weather and forecast as a png, or if you use it like this:
+```
+wget -O- -q wttr.in
+
+```
+
+You can replace `curl` with `wget -O- -q` in all the commands below if you prefer Wget over cURL.
+
+Specify the location:
+```
+curl wttr.in/Dublin
+
+```
+
+Display weather information for a landmark (the Eiffel Tower in this example):
+```
+curl wttr.in/~Eiffel+Tower
+
+```
+
+Get the weather information for an IP address' location (the IP below belongs to GitHub):
+```
+curl wttr.in/@192.30.253.113
+
+```
+
+Retrieve the weather using USCS units:
+```
+curl wttr.in/Paris?u
+
+```
+
+Force wttr.in to use the metric system (SI) if you're in the USA:
+```
+curl wttr.in/New+York?m
+
+```
+
+Use Wget to download the current weather and 3-day forecast as a PNG image:
+```
+wget wttr.in/Istanbul.png
+
+```
+
+You can specify the PNG
+
+**For many other examples, check out the wttr.in[project page][2] or type this in a terminal:**
+```
+curl wttr.in/:help
+
+```
